From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] infiniband: cxgb4: use %pR format string for printing resources Date: Mon, 01 Feb 2016 17:42:02 +0100 Message-ID: <2278867.O0SM8nbQp0@wuerfel> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Doug Ledford , Sean Hefty , Hal Rosenstock Cc: Steve Wise , linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org List-Id: linux-rdma@vger.kernel.org The cxgb4 prints an MMIO resource using the "0x%x" and "%p" format strings on the length and start, respective, but that triggers a compiler warning when using a 64-bit resource_size_t on a 32-bit architecture: drivers/infiniband/hw/cxgb4/device.c: In function 'c4iw_rdev_open': drivers/infiniband/hw/cxgb4/device.c:807:7: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] (void *)pci_resource_start(rdev->lldi.pdev, 2), This changes the format string to use %pR instead, which pretty-prints the resource, avoids the warning and is shorter.
